Attach the Rail to the Header Bracket

• Position the opener on the garage fl oor below the header
bracket. Use packing material as a protective base.
NOTE: If the door spring is in the way you'll need help. Have
someone hold the opener securely on a temporary support to
allow the rail to clear the spring.
• Position the header/rail bracket against the header bracket.
• Align the bracket holes and join with a clevis pin 5/16"x2-3/4"
as shown. Spacer can be installed on either side of rail.
• Insert a ring fastener to secure.
